CONTROL DEVICE FOR AUTOMATIC PLAYING INSTRUMENTS.

Application filed June 17, 1911.

To all whom it may concern:

Be it known that I, J osnrn SorIwEnTNnR, a citizen of the United States,and a resident of New York, county of New York, and State of New York,have invented certain new and useful Improvement-s in Control Devicesfor Automatic Playing Instruments, of which the following is aspecification.

My invention relates to improvements in automatic playing instruments,and it is especially designed as an improved means for the manualcontrolling of the accentuating or solo devices of automatic pneumaticplaying instruments.

One object of my invention is to provide an improved arrangement wherebyany note or set of notes may be selected at will, for the purpose ofaccentuatio-n, and whereby these notes or sets of notes which are to beaccented may be changed at will, and whereby a plurality of such notesor sets of notes may be selected at will for simultaneous accentuation.

Further objects, features and advantages will more clearly appear fromthe detailed description given below, taken in connection with theaccompanying drawings which form a part of this specification.

My invention in its broader aspects, was previously described in myprior application, Serial No. 535,585, filed December 30, 1909.

Referring to the drawings, Figure 1 is a transverse vertical sectionthrough the main operating parts of my improved arrangement. Fig. 2 is alongitudinal vertical section taken on the line IIII of Fig. 1. Fig. 3is a. plan view of the parts shown in Figs. 1 and 2, certain parts beingomitted 'to save space. Fig. 4 is a detail section taken on the lineIVIV of Fig. 1. Fig. 5 is a detail view of parts shown in Fig. 2. Fig. 6is a front elevation of parts shown in Figs. 1, 2 and 3. Fig. 7 is anend view of the same, and Fig. 8 is an opposite end view of the same.

Referring to the drawings, 1 represents suitable frame work supportingthe blocks 2 and 3. The blocks 2 and 3 are provided with a plurality ofair passages 4 and'5, as shown in'Fig. 1. On top of the blocks 2 and 3are arranged a series of valves, 6 and 7, arranged to close the ends ofthe wind ducts 5. The valve closures 6 and 7 are carried Specificationof Letters Patent.

Serial No. 633,753.

upon movable arms 8, fulcrumed at 9, and entirely surrounded by aflexible membrane 10, so that a plurality of small bellows are formed,which cover the upper ends of the wind passages 4 and 5. Each valveclosure 6 and 7, is designed to open and close the wind passage 5, toconnect and disconnect it with its corresponding wind passage 4, openinginto the same small bellows. Springs 11 normally force the valveclosures 6 and 7 downwardly so as to close the valves. Each of themembers 8 is provided with a member 13, rigid therewith.

Fulcrumed in the frame work at 14, and arranged in a horizontal plane,are a plurality of wire lever members 15. Each wire lever member 15 isbent upwardly, as at 16 (see Fig. 4), and then bent longitudinally, asat 17. The bent over ends 17 engage beneath the projecting arms 13, asclearly shown in Fig. 4. On each side of the fulcrum 14 the wire levermembers 15 are bent in'a U or V shape form, as clearly shown in Fig. 3.At the extreme front end of the wire lever members 15, they are bentstraight out, as shown in Fig. 3. It will therefore be clear that bypushing up on the front ends of the wire lever members 15, the portions17 thereof will be forced upwardly, and thus raise the valve closures 6to open the valves. In a similar manner in operating the valve closures7, there are provided a plurality of lever members 18, fulcrumed in thesame plane at 14, as the lever members 15, but having their inner endsbent downwardly, as at 19, and then longitudinally, as at 20, to engagethe under side of the arms 13, for operating the valve closures 7. Inother respects the lever members 19 are similar to the lever members 15.The lever members 15-48, are fulcrumed by passing them through openingsbetween two plates, at 14.

Sliding upon two fixed rods 21 and 22, are two frames 23 and 24. Eachframe 23 and 24, carries a fixed handle as at 25, and a movable handleas at 26, cooperating therewith. In the frame 24 the movable handle issecured to an oscillating rod 27, journaled in the frame. Theoscillating rod 27 has secured to its opposite end a member 28, carryinga cam face 29, and an arm 30. Pivoted to the frame 24, at 31, isarocking arm 82 having a. cam face 33 thereon. The cam face 29 isadapted to engage with the cam face 33, so as to rock the arm 32 againstthe action of the spring 34. The opposite end of the arm 32 has two thinsteel members 35 and 36, attached thereto, as clearly shown in Fig. 2.The member 35 is provided with cam faces 37 for engaging the front endsof the wire lever members 15 and 18. It will therefore appear that bymoving the frame or member 24, the cam faces 37 will engage the frontends of the lever members 15 and 18, to raise the same, and therebyraise the opposite ends of the lever members 15 and 18, so as to raisethe corresponding valve closures 6 and 7.

In order to lock the valve closures 6 and 7 in open position, I providea plurality of lever members 38, fulcrumed in the frame at 39 (see Fig.1), and having their front ends bent to the left, as at 40, and thenstraight outward, as shown in Fig. 3. The inner ends of the levermembers 38 are bent upwardly as at 41, and springs 42 engage theseupwardly extending portions, and normally tend to force them toward theleft, in Fig. 4, that is, they normally tend to force the uprightportions 41 beneath the lever members l5 and 18, after they have beenraised. This is for the purpose of locking the lever members 15 and 18in their raised positions, to lock the valve closures 6 and 7 in theiropen positions, respectively. The steel member 36 carried by the slidingmember 24, is provided with cam faces 43, which engage the lever members38 for the purpose of operating the same, as the frame or carriage 24 ismoved back and forth upon the rods 21 and 22.

The carriage 23 carries exactly the same parts as already described uponthe carriage 24, except that the parts are reversed, as shown in Fig. 2.It is therefore unnecessary to further describe the same parts which areon the carriage 23.

Referring to Fig. 2, and the lever members 18, 15, and 38, as shownthereupon, and beginning at the left hand end of the rows of levermembers 18, 15 and 38, the first lever member 18 is locked by means ofthe first lever member 38. It will therefore be seen that upon movingthe carriage 24 in a left hand direction, the cam 36 strikes the levermember 38, a short time before the cam 35 strikes the lever member 18.Therefore the lever member 38 will be rocked before the lever 18, and ina similar manner, when moving the carriage in a reverse direction, thelever member 18 will be rocked after its corresponding lever member 38has been rocked. Therefore, upon moving the carriage 24 to the left, inFig. 2, the cam 35 raises the lever members 15 and 18, and consequentlythe valve closures 6 and 7, and the springs 42, force the locking levermembers 38, with their upright extensions 41, beneath the lever members15 and 18, as shown at 44, in Fig. 4, and thereby lock the valves inopen position. Since in this part of the operation the cam 36 actsbefore the cam 35, the lever members 15 and 18 remain locked in theupper position. If now, the carriage 24 is moved in the oppositedirection, to the right in Fig. 2, the cam 35 operates first, but sincethe lever members 15 and 18, to the right of it, are already in raisedposition, and locked in that position, there is nothing for the cam 35to do. It therefore merely passes under the front ends of these levermembers. However, the cam 36 following in its action, rocks the levermembers 38 against the action of the springs 42, so that the uprightportions 41 are withdrawn from underneath the lever members 15 and 18,so that the lever members 15 and 18, drop to their original positionunder the action of the springs 11. It will therefore be seen that bymoving the carriage 24 to the left, in Fig. 2, all valves 6 and 7, leftbehind it, will be opened, and locked in open position, but upon movingthe carriage 24 in the opposite direction these valves will beconsecutively closed. The carriage 23 operates in a similar manner toopen and close the valves corresponding to lever members 15-18, but actsin the reverse direction, so that ordinarily, if we start with the cams35 directly behind one another, there may be no lever members 15 or 18raised, and no valves opened. Then upon separating the carriages 23 and24, all valves will be opened corresponding to the lever members 15 and18, between the cams 35. These carriages may be moved back and forth in.25, thereby rocking the shaft 27, and the member 32, so that the cams35 and 36 are rocked downwardly out of engagement with the lever members1518 and 38. The cams in this rocked position are shown clearly in Fig.5. Slidably mounted in each frame work 23 and 24, is a sliding bar 45,which has rigidly secured thereto a depending arm 46. A pin on the arm30, secured to the rocking shaft 27, engages a slot on the depending arm46, so that as the member 28 is rocked, the depending arm 46 is movedlongitudinally, so as to slide the sliding bar 45 back and forth. Eachbar 45 slides in suitable guide ways in the frames 23 and 24. Each bar45 is normally pressed clownwardly by a spring 47 At one end the bar 45carries a projection 48 which is designed to engage at certain times,the wire lever members 38 instead of the cam 36. Upon the rocking of theshaft 27, in order to throw downward the cams 35 and 36, the

11&

bar 45 is thrown to the right, in Fig. 5. The bar 45 is provided with acam face 49, which engages a co5perating cam face or roller 50, so thatthe left hand end of the bar 45 is raised, as shown in Fig. 5. Thus itwill be seen that supposing the carriage 24 is stationary, as in Fig. 5,the mere operating of the handle 26, to rock the member 28, will lowerthe cams 35 and 36, and raise the projection 48. Thus, referring to Fig.5, if the Wire lever member 15 be locked in its upper position, theprojection 48 will move upwardly and strike the corresponding levermember 38 to unlock the lever member 15. Upon releasing the handle 26under the action of the spring 34, the cam 35 moves up wardly to engagethe lever member 15, to raise it. At the same time the projection 45moves downwardly and the cam 36 moves upwardly. But the cam 36 beingspaced longitudinally from the cam 35 so that it does not act untileither before or after the cam 35 has acted in the longitudinal movementof the carriage 24, the cam 36 will not, while the carriage 24 isstationary, operate upon the proper locking lever 38 to unlock the lever15. It will therefore ap pear that with the carriage 24 stationary, thecam 35 may be used to raise any one of the lever members 15 or 18, andthen the same member unlocked without moving the carriage 24, by merelythrowing the handle 26, when the projection 48 will move upwardly, toengage the corresponding lever member 38, to unlock the lever member 15or 18, as the case may be.

The operation of the parts so far men tioned, may be described asfollows: The raising of one or more of the valves 6, 7, &c., causes thecorresponding wind passages 4 and 5 to be connected, and this causes acorresponding note or set of notes to be accented, whenever these notesare caused to be played by the perforated music sheet or similar device.Means whereby a perforated music sheet will cause the production ofnotes are well known, and therefore need not be described here. Also anywell known means for accenting certain notes being played may be used.However, I prefer to use arrangements such as shown in my priorapplication, Serial No. 596,196, filed December 8, 1910, or Serial No.614,593, filed March 15, 1911, or Serial No. 617,968, filed March 30,1911.

.By the use of any of these arrangements,

the raising of any one of the valve closures 6, 7, &c., may be made tocause the corre sponding note or notes to be accented when it is played.In order to select the notes to be accented, it is therefore onlynecessary to select certain of the valves 6, 7 and open the same. Forthis purpose the carriages 23 and 24 are moved by means of the handles25, so that a certain number of the wire lever members 15, 18, &c., areincluded between the cams 35. With the cams 35 working in their normalraised positions all of the lever members between these cams will beraised, and thus all of the notes corresponding to the lever membersbetween these cams will be accented, since the lever members are heldlocked in their raised positions by means of the lever members 38. Thusany note or set of notes may be selected at will, at any part of theregister of the instrument, whether in the bass or treble. If now it isdesired to accent a certain note or set of notes in the bass, and alsoan independent note or set of notes in the treble, then the carriages 23and 24 are moved to the bass portion of the register and separated, toselect the desired notes there for accentuation, then the handles 26 arepressed, thus withdrawing the cams 35 from operation, and then thecarriages 23 and 24 are moved to the treble portion of the register.This movement does not operate any of the lever members 15 and 18,because the cams 35 are withdrawn from operation. After the carriages 23and 24 have been moved to the treble portion of the instrument they arethen separated to select the set of notes which it is desired to accentat that portion of the register. If it is only desired to accent onenote at a time at the treble portion'of the register, only the carriage24 need be moved to that por tion of the register, when upon releasingthe handle 26 thereof, its cam 35 will'be moved upwardly, and may bemade to engage the proper lever member 15 or 18, so as to cause thecorresponding note to be accented. Ordinarily, the mere pressing of thehandle 26, which causes the cams 35 and 36 to be moved downwardly, doesnot unlock the particular lever member 15 or 18, which has been raised.This is because the cam 36is displaced as to the cam 35, with respect tothe corresponding lever members. But even with the carriage 24stationary, the particular lever member 15 or 18, which happens to beraised,may be unlocked by movement of the handle 26, because movement ofthe handle 26 raises the projection 48, to engage the locking levermember 38, so as to unlock the particular lever member 15 or 18, whichhappens to be raised. This is shown clearly in Fig. 5. It will thus beseen that by means of the devices described one is enabled to select anynotes which it is desired to be accented, and also one may select a noteor set of notes at one portion of the instrument, and also a note or aplurality of sets of notes at another portion of the instrument, forsimultaneous accentuation.

In order that means may be provided for conveniently regulating thetempo of the instrument, I provide a scale 55, carried by a carriage524-, and rigid therewith. Sliding over the scale is a pointer 56. Thepointer 56 is rigid with a shaft 57, and has a thumb piece 58 at itsupper end. The shaft 57 is journaled in the carriage 2e, and extendsrearwardly. Rig idly secured to the rear end of the shaft 57 is an arm58, which carries on its outer end a forked member 59 (see Fig. 2). Theforked member 59 is pivotally connected to the end of the arm 58, bymeans of a pin 60 (see Fig. 6). The forked member 59 engages a rod 61,which has rigidly secured to each end thereof, arms 62. The arms 62 arepivoted to the frame work, as at 63 (see Fig. 3), and at their oppositeends carry weights 6st. It will thus appear that by moving the pointer56 over the scale 55, the shaft 57 is rocked, thereby moving the arm 58up and down, and with it the forked member 59. The forked member 59 thuscarries the rod 61 up and down, thereby rocking the arms 62 about theirpivots 63. Any suitable means may be connected to the arm 62, in orderto regulate the tempo of the instrument, such means being well known inthe art. By the arrangement just described, the tempo may be regulateddirectly from the carriage as although the hands of the operator may beboth busily engaged, one upon the carriage 52 i, and the other upon thecarriage 23, it will be seen that the tempo may be regulated withoutremoving the hands from the carriages. In other words, as the carriage24 is moved horizontally from place to place, the forked member 59slides along the rod 61,but does not move the rod. But upon movement ofthe pointer 56 while the carriage is in any posit-ion, or even while itis moving, the rod 61 is moved up and down, thereby rocking the arms 62,to regulate the tempo, in any well known manner.

In order that means may be conveniently provided for varying the amountof accenting, or the volume of the notes being accented, and also thevolume of the accompaniment notes, I provide a series of lever members65, 66, 67, 68, 69 and 70. These lever members are made of strong wire,bent in a U shaped. form, as shown in Fig. 3. Each of these levermembers is pivoted to the frame, as at 71 and 72. Referring to Figs. 3,6, and 7, each of the lever members, at its left hand end, carries avalve closure 7 3, each designed to cover the outer end of a windpassage in the wooden frame work, at 74-. These passages in the woodenframe work at 74c, terminate in wind ducts 75. Springs 76 normally forcethe valve closures 73, downwardly, to close the opening of the windpassages in the wooden frame 74;. The other ends of the lever members65, 66, 67, are engaged by a rocking member 77 (see also Fig. 8),

which is provided with a plurality of cam faces 79, 80 and 81, and alsowith a plurality of projections 82, 83 and 8 k. Thus referring to Fig.8, if we force the left hand end of the lever member 67 downwardly, theright hand end moves upwardly, forcing to the right the member 77, whichis pivoted at 85, until the right hand end of the member 77 goes abovethe projection 8 L, when the spring 86 will force the member 77 to theleft, with the projection 84: underneath the lever 67, thereby lockingthe lever member 67 in this thrown position. As shown in Fig. 8, thelever is shown locked in its thrown position, being held there byengagement with the projection 82. It will be seen that by throwingeither of the levers 65, 66, 67, its corresponding valve closure 73 israised, and locked in its upper position. If now the lever 65 is thrown,and locked in its thrown position, as shown in Fig. 8, and then it isdesired to operate the lever 66, and at the same time release the lever65, the left hand end of the lever 66 is pressed downwardly, therebythrowing the right hand end of the lever upwardly until it engages abovethe projection 83. This action throws the member 77 backwardly,suflicient to allow the end of the lever 66 to pass the projection 63.This movement of the lever 77 upwardly, may be sufficient to release thelever 65, by withdrawing the projection 82 from beneath its right handend. But if it is not sufficient for this, a slight further movement ofthe lever 66, causes its right hand end to engage the cam face 80, sothat a slight further movement of the lever 66, rocks the member 77still further backward, until the projection 82 is withdrawn frombeneath the lever 65, thereby releasing the same and allowing itscorresponding valve 73 to close. Thus by pressing down, or throwing, anyone of the levers 65, 66 or 67, any other one of these levers whichhappens to be locked in its thrown position, will be released. In asimilar manner I provide a rocking member 87, pivoted at 85, normallyheld in its forward position, by a spring 88, and provided withprojections 89, and cam faces 90, for cotiperating with the inner endsof the lever members 68, 69, 7 0. These operate in the same manner asthe lever members 65, 66, 67, so that any one of these lever members 68,69, 70, may be thrown, and locked in its thrown position, and upon theoperation of any other one of these lever members, the first will bereleased. The operation of the lever members 65, 66, 67, is designed tothrow into operation any one of three different pressures or degrees ofexhaust for operating the power pneumatics for the notes being accented,thereby controlling the volume of the accentuation. This may be done bymeans of any suitable pneumatic apparatus controlled by raising of thevalve closures 73. Such an arrangement is shown in my prior application,Serial No. 631,409 filed June 5, 1911.

Of course if my improvements are used in connection with organs theusual organ devices for varying the volume will be used instead of thoseusual in automatic pianos and other instruments. In like manner theoperation of the lever members 68, 69, 70, may be made to cause any oneof three different pressures or degrees of exhaust, to be thrown intooperation with respect to the accompaniment notes, in order to vary thevolume of the accompaniment.

Stops 92 are provided, for limiting the movement of the members 77 and87, in a forward direction, in case the lever members 65, &c., shouldall become disengaged therefrom.

Although I have described my improvements in great detail, neverthelessI do not desire to be limited to such details, except as clearlyspecified in the appended claims, since many changes and modificationsmay well be made without departing from the spirit and scope of myinvention in its broadest aspects.
